To all whom t may concern.'

IBe it known that I, YMAURICE LAGHMAN, a citizen of the United States, and a yresident I 4of New York, in the' county of New York and State of New York, have invented certam new' and useful Improvements in Methods of Making 'Wire Wheels, o f which the following is a specification.

My lnvention relates to-the manufacture of wire wheels the spoke portion of which consists of orembodies as apart thereof a continuous length of wire welded tothe rim and to the hub in two different planes axially displaced with reference to 'one another as described and shown in my companion application filed by :meFebruary 8th, 1918, Serial No.v 215,981. i

My present` invention relates more par- `ticularly tothe manner of forming the wire portion vof the wheel so as to provide the bendsor loops which serve for attachment to therim and the connecting bends or loops connecting contiguous spoke lengths at their inner ends where they are welded or secured to the hub in the different planes.

vIn the accompanying drawings:

Figure 1 shows diagrammatically the. first stage ofthe operation and Fig. 2 the vsecond stage thereof.

ig. 3 shows a cross-section of the wheel -in which the wire is embodied as the spokel portion thereof, and Fig. 4 a side elevation of said wheel.

Referring first to 3 which typies a particular form of wheel in the construction of which my invention may be employed, 1

indicates a suitable metal hub ofthe wheel and 2, 2 indicate flanges 'thereof which are l preferably provided with the circumferensist .in the electricalwelding' oft e side Vcircumferential ribs ,or projections v5 to` as-l hich the'wire comprising thelspokes may tial sideI ribs or projections `'servin to as- 1 518' i bends ewiges@ Spoke lengthen therme-MS.

Y where said spokes are welded as to some of them to the side ribs 3 of flange 2 and as to others to the said ribs v3 of liange 2', the welding being either in the loop part 8 8 itself or in a portion of the spoke length contiguousthereto. Thel loops or bends 8 8" may rest on the barrel of the hub as shown and as described in my 'companion application above referred to. Y i

As will be' seen, the wire portion ofthe wheel is disposed to strengthen the wheel againts torsional or' twistlng strains. In forming up the wire portion according to my present invention I bend up, as shown in Fig. l, a continuous length of wire into .zigzag shape, the wire being disposed in one plane which may be considered as the plane 'of the paper and so as to provide the bends or loops 8 8 which connect contiguous spoke lengths at theirinn'er ends where they are secured to the hub. To form' the loops 7 the skeleton or zigzag is bent up transverselyto the plane of the zigzag into the shape, Fig. 2, onthe lines'12, 12, after which the portion comprising the loops 7 may be spread o'ut or separated'into the circular formv required that it may occupy the space betweenthe hub and rim and with asymmetrical disposition of the spokes in said "space asshown in` Fig. 4. Prior to the applicationl of thebent` 85 length of wire into the spoke portionof a3 'wire wheel, consisting in bending the 'length of wire into a zigzag skeletonor frame to 'provide loop'sor bends at the hublyends of 'spoke lengths and then bending the zigzag frame intermediate said loops and transversely to the plane of the zigzag to form loops or bends for attachment yof,the outer ends of the spoke lengths the rim. 2. The method of forming a continuous,

metal wheel, consisting in bendmg the wire into zigzag form to produce connecting loops' VVorbends between the inner lengths,.bending .the zigzag transversely to formfloops or" bends for attachment of \th`e outer ends of thespoke lengths tothe rim and Vspreading out the 'form thus produced ,by. separatng the latter 'loops into their 'length of wire into the spoke yportion of a ends of spoke lll@ spaoed circumferential relation in the linished Wheel.

3. The method of forming a continuous length of Wire into the spoke portion of a metal wheel, consisting in bending the Wire into zigzag form to produce connecting loops or bends between the inner ends of spoke lengths, bending the zigzag transversely to form loops or bends for attachment of the outer ends of the spoke lengths to the rim and spreadin out the form thus produced by separating t e latter loops into their spaced circumferential relation in the finished Wheel and Welding the ends of the Wire length together.

4. The method of manufacturing Wire l Wheels consisting in forming all the spoke members from a single length of Wire by bending the Wire into zigzag form and then doubling over one art with relation to the other and electrica ly Welding the Wire to both the wheel rim and the Wheel hub.
